Four species of Rhizocephala were found on crabs from the intertidal rocky shore of Sanriku, northern Honshu: Sacculina yatsui Boschma, 1936 from Pachygrapsus crassipes; Sacculina sp. from Hemigrapsus sanguineus; Peltogaster paguri Rathke, 1842 from Pagurus maculosus (new host); and Peltogasterella gracilis (Boschma, 1927) from Pagurus filholi (new host), P. maculosus (new host) and P. middendorffii. The bopyrid isopod Athelges takanoshimensis Ishii, 1914 also occurred on P. filholi and P. maculosus (new host). These parasitic crustaceans are recorded for the first time from the Pacific coast of northern Honshu.
